@inalittlewhile Thanks for inquiring. This is known as a Coin Claw. Produced by famous knife maker Serge Panchenko. The claw swivels out further. In which you can hold the circular part in your closed fist. The claw will stick out between your fingers in a closed fist. Looking like a bear claw would. The claw folds all the way in making this knife looks like a circular coin. This is a full custom design produced in small batches. Highly collectible.
